Hi doctor, I had fever on 13th and 14th of May, then on 15th no fever but I observed 2 drops of blood from urine. I had blood test for uric acid, urea, BUN, creatinine, Calcium, phosphate, sodium, which all was normal. I showed a general physician, he asked me to have usg and urinalysis, usg showed everything normal with distended gall bladder and urinary bladder. I am having pain while urinating at the tip of glans since last 4 days but it has increased since last 24 hours. urinalysis reports have not come yet. Is it kidney stones or urinary tract infection? Doctor has given me nifty sr 100 for 7 days. Should I start it?
